Bug 12929 – Empty union followed by field causes ICE due to offset of 0.

Sample: struct Foo { union { } int bar; } Output: dmd: argtypes.c:405: virtual void toArgTypes(Type*)::ToArgTypes::visit(TypeStruct*): Assertion `t1 || f->offset == 0' failed. Aborted (core dumped) While the above example is fairly useless seeming, it makes more sense with variable length templates to generate a union.

Doesn't happen on git HEAD anymore (at least not with the code posted here). Has recent compiler changes obscured this bug?
